Description of the invention (1) [Industry application field] The present invention relates to the target displayed on the display screen is simulated by the gun, and the target position is clicked. A target video game device that controls the progress of the video game in relation to the position of the target. [Advance Technology] This type of prior-art target video game device is similar to a light-receiving unit in a simulated gun. When the player buckles the board shot of the simulated gun, the display screen of the display device turns white, and the corner of the display device sequentially orders the white screen. Raster scan is performed to detect the target position at the time when the light-receiving unit receives light from the entire raster scan (that is, the raster scan position). [Problems to be solved by the invention] However, the above-mentioned prior target video game device has the following problems: There are: (1) When the board shot of the simulated gun is pulled, the display surface turns white, and the light intensity of this white screen It is easy to irritate the eyes, not only hinders the picture quality of the video game screen, but also may cause the player's eyes to flicker. (2) The mid-target position cannot be detected without switching to the white screen. Therefore, when the continuous target detection is required for the mid-target position, such as the mid-target position display, it may be difficult to detect the continuous target. That is, even if the end of the video game is displayed alternately with the end of the white video, it can only be detected at a rate that rewrites the video game screen at an interval of one cycle. Therefore, the screen displayed on the display device is guided by the reflection of the translucent mirror (please read the precautions on the back before filling in this page). Binding.

Therefore, the structure is complicated and assembled, and the arrangement requires precision requirements. In addition, there is also a proposal to detect the position of the light source provided in the center of the target with a semiconductor position detection unit provided inside the gun to detect the middle target position of the gun (Patent Open 6 0 — 1 1 1 6 7 (Gazette No. 6), but this kind of gun shooting device is because the target is fixed, so the light source can be arranged in the center, that is, a fixed position, as for the video game screen that changes from moment to moment, even with a target whose position changes at any time The target video game device is difficult to apply. The present invention has been made in view of the above problems, and its object is to provide a target video game device that can accurately detect the center position of the simulated gun with a simple structure. [Means to solve the problem] The invention claimed in item 1 is applicable to display devices having a display screen with a display target, a simulated gun device to shoot a target, and a target video game device. The above purpose is to set and arrange at least one eyepiece near the display screen, to capture the imaging means in the imaging area of the muzzle direction of the simulated gun means, and to detect the position of the target within the image obtained by the imaging means Means and the position of the target detected by the position detection means, this paper scale is applicable to the Chinese National Standard (CNS) A4 specification (2 丨 ο X 297mm) (please read the precautions on the back before filling this page).

The CCD camera 13 is arranged in the simulated gun 10 such that it can capture a scene directly in front of the muzzle direction of the simulated gun 10, and the imaging signal of the CCD camera 13 is output to the position detection circuit 6 . In this embodiment, the light receiving surface of the CCD camera 13 and the central axis along the hatch direction (equal to the connecting axis between the center target position on the display screen 1 a and the simulated gun 10) are in a state of being orthogonal. 14 is an imaging lens and 15 is an infrared filter lens, which are respectively arranged in front of the light receiving surface of the CCD sensor. In more detail, the focal distance of the imaging lens 14 and the distance from the CCD sensor are determined to be in a state where a bright portrait can be formed on the light receiving surface of the CCD sensor. On the other hand, the infrared filter lens 15 only allows light having a wavelength in the infrared region to pass through, and preferably, only allows light corresponding to the wavelength of infrared light of the infrared projection device 4 to pass through. FIG. 3 is a block diagram for explaining the position detection circuit 6 in detail. The two-state processing circuit 62 converts the day image captured by the CCD camera 13 into a high-level, low-state two-state data and guides it to the frame storage. In this process, the bistate level (that is, the threshold value) is to change the reference voltage according to the light sensitivity.

Therefore, in terms of pixel width, the hXv counting block B L is specified. Furthermore, by selecting the lens or the brightness of the infrared light spot LS :, L Sr provided on the imaging surface of the CCD camera 13, the LED data 01 (as shown by the slanted part of FIG. 4 (c)) can be A plurality of addresses exist. By obtaining the plurality of points in this way, it is possible to identify the infrared light spot data and other clutter. Next, FIG. 3 and FIG. 4 (c) will be described for the accumulation processing. Since the read address generation circuit 64 specifies the address of the counting block BL, the memory contents of the address are sequentially read from the frame storage 6 0 1 (or 6 0 2), and the read address at this time is directed to the accumulation circuit 6 8 1. Whenever the point (high level data) of the infrared light spot Di is read out from the frame storage, the count value of the point counter 6 8 3 will increase as a result of this point data, and it is led to the latch circuit 6 8 2. The latch circuit 6 8 2 only latches the address value output by the accumulation circuit 6 8 1 when inputting the data, and at the same time, guides this value to the accumulation circuit 6 8 1 ° again. Thus, whenever the frame stores 6 0 1 Output point data, the address value of the point data is memorized and output to the accumulation circuit.

V. Invention Instructions (11) 6 8 1 and exhausted. As a result, the point counter 6 8 3 takes the number of points existing in the counting block BL, and the latch circuit 6 8 2 takes the accumulated value of the address where the point exists. However, the position detection CPU 61 has finished designating the address of the counting block BL, and then takes in the data obtained by the latch circuit 6 8 2 and the point counter 6 8 3, and judges by the number of points whether it is infrared light point image data or miscellaneous Wave, the cumulative value is divided by the number of points to calculate the center address of the point (H c, V c). This center address becomes the center of gravity of the entire survey surface, and the counting block is set or the target position is detected based on this position data. As for the determination of infrared spot data or clutter, for example, the threshold value of the number of points can be set, and the number of points above the threshold value can be used as infrared spot data. In addition, the calculation of the center address described above is performed by a hardware configuration, and the position detection CPU 61 may only transmit the calculation results of H and V. Furthermore, instead of using absolute coordinates, the relative coordinates of the coordinates may be relative coordinates based on the reference coordinates, and finally added to the reference coordinates to obtain the destination coordinates. In doing so, the number of digits is reduced, and there are advantages of hardware addition processing that can speed up. Next, referring to the flowcharts of FIGS. 5 to 9 and FIGS. 10 and 11, the operation of the target video game device of the present embodiment will be described. (1) Video game processing (FIG. 5) FIG. 5 is a flow chart for explaining the operation of the program executed in the video game control circuit 5.

Description of the invention (12) Data processing, for example, the symbols on the video game screen should be made of polygons, shell 11 contains polygons deal with. Video game data processing is carried out every field period, and the video signal is sent to the projector 2 by the video game control circuit 5 for each field period to overwrite the video game screen. In step S3, the board strike signal sent by the simulated gun is confirmed, and as a result, it is determined in step S4 whether the board strike signal is in the on state. If the board strike signal is ON, that is, the player has a board shot 11 that has a simulative gun 10, then step S5 is entered, and if the board hit signal is OFF, that is, the player does not have a board shot 11 that has a spur simulated gun 10. Go to step S9. In step S5, the data of the middle target position (H, V) detected by the position detection circuit 6 is taken. The operation of the position detection circuit 6 will be described later. In step S6, it is determined whether the target position taken in step S5 is (Η, V) = (〇, 〇), that is, outside the range of video games, if it is determined to be positive, then step S 8. If the judgment is negative, enter Buchen S7. In step S7, data processing according to the detected middle target position is performed. As an example, there are counts of the number of hits, whether to hit the rake or not, and the number of remaining sub-bits. On the other hand, in step S8, processing is performed when the target position is outside the video game screen. In this case, the processing does nothing, or "missing" is displayed, but in this embodiment, the bullet boring processing of the gun 10 is performed. In step S9, the final confirmation is performed according to the predetermined video game rules, etc. If the termination conditions are satisfied, the video game program is completed, otherwise it returns to step S2 to repeat the above process.

Therefore, according to the target video game device of this embodiment, the infrared light spots LS, LSr arranged at the left and right ends of the video game screen are captured by the CCD camera 13 built in the simulation gun 10, and the simulation is detected based on the imaging position The middle target position of the gun 10, so there is no need for the previous target video game device. When the simulated gun sends a boarding signal, the display screen needs to be white, and the video game screen can be continuously displayed to improve the quality of the video game screen. Avoid blinking the player's eyes. With the target video game device of this embodiment, it can be used as a copy of the video game screen.

Description of invention (2〇) Write cycle (in this embodiment is the field cycle ) Position detection that is synchronous and continuous to the action interval, the position display when the target position is hitting, etc., when the target position is required to be displayed continuously, the continuous position detection can be done substantially. This is explained with reference to FIGS. 12 and 13; FIG. 12 is a time chart of the main signals of the prior target video game device, (a) is the extinguishing signal of the display device, (b) is the I / O-READ signal, (c) is the board strike signal of the gun, (d) is the output signal of the light-receiving unit provided at the analog gun end, (e) is the latch signal of the HV counter. When the board strike signal is output, the video game screen is switched to a white screen and the screen flickers. At the same time, the daylight plane is raster-scanned, and after the light-receiving unit receives this raster-scanned light, the HV counter latches. When the raster scan of one frame is completed, the position of the middle target is detected due to the latch time of the HV timer and read into the game control circuit. Therefore, since there must be a raster scan of the screen from the output of the simulated gun's boarding signal to the completion of the position detection, the position detection cycle will never be faster than the video game rewrite cycle. On the other hand, FIG. 13 is a time chart of the main signals of the target video game device of this embodiment, (a) is the extinguishing signal of the projector 2, (b) is the extinguishing signal of the CCD camera, (c) is the position by The mid-target position detection signal output by the detection circuit 6 is (d) the board shot signal of the analog gun 10, and (e) the I / O — READ signal of the video game control circuit 5. The extinguishing signal of the projector 2 is synchronized with the extinguishing signal of the CCD camera 13, and the mid-target position signal is output every field period. When the simulated gun 10 outputs a board strike signal, the mid-target position at that time is read into the video game control circuit 5. Therefore, the field cycle and the position detection cycle can be made once, and the continuous performance detection of the middle target position becomes the paper standard applicable to the Chinese national standard (CNS> A4 specification (210X25 »7mm) ~ -23-(please read the back (Notes need to fill out this page).

Moreover, since this embodiment uses the projection of two infrared light spots LS :, The infrared projection device 4 of the LSr and the CCD camera 13 built in the simulation gun 10 detect the position of the middle target, so it is simpler to construct than the previous target video game device in which the light emitting units are arranged in a matrix, and it is measured in advance Infrared point LS], the distance between LSr and the size of the display screen 1 a (essentially the width of the display screen 1 a), the position of the middle target can be detected, so assembly and configuration do not require precision work. And, this The embodiment uses the infrared CCD to detect the position of the infrared light spot, so it is not easily affected by external light with a wavelength in the visible field, and it has strong resistance to external clutter. In addition, in this embodiment, not only can the position of the center target on the display screen 1 a be estimated, but also the distance D between the simulated gun 10 and the display screen 1 a can be estimated. D provides various forms such as scoring to provide more interesting video games. In addition, the details of the target video game device of the present invention are not limited to the above-mentioned embodiment, and various modifications can be made. For example, the above In one embodiment, the mid-target position is detected by the imaging positions of two infrared light spots, but the number of infrared light spots is not limited. Moreover, the means for generating infrared light spots can be appropriately selected from well-known means, for example Infrared light emitting diodes (I RED), lasers (gases, liquids, solids, semiconductor lasers), incandescent light bulbs with luminous properties in the infrared field, etc. Also, the position of the means for generating infrared light spots is also available It is not limited to an embodiment. For example, if an embodiment adopts a form in which the optical path is folded back through a semi-transparent mirror, the size of the translucent paper is suitable.

Invention Description (22) It is also possible to arrange the infrared light spot behind the mirror. If one kind is adopted, the CCD sensor and the processing circuit are formed on one substrate, the so-called CCD card camera is not only lightweight but also Improve maintenance. On the contrary, the simulation gun is only equipped with a CCD sensor, and it is also possible to form all the processing circuits on the substrate without the position detection circuit. Moreover, the above embodiment uses the CCD photography of the infrared spot as the target The device picks up to detect the middle target position, but the target is not limited to the infrared spot. For example, ultraviolet rays, sound waves, electromagnetic waves, etc., can be used to radiate forward from the screen. If the player is allowed to see and is easily affected by external light, then the structure that radiates visible light from the screen can also be used. .
